/* KeyAssist — gateway-page.css
   Loaded only by the static /gateway topic page (scripts/prerender_gateway.py),
   on top of case-page.css, whose tokens (--bg / --panel / --border / --text /
   --muted / --accent) it reuses so the two static surfaces stay one design.

   The verdict colours are the load-bearing part: a locksmith scanning this
   page is looking for one thing — can I write over OBD or not — so `clear` and
   `blocked` must be separable at a glance, and never by hue alone (the label
   text carries the meaning too, and forced-colors mode keeps the border). */
